| Abstract [eng] |
Objective: This study sought to define the prognostic value of myocardial viability in patients with severe ischemic heart failure, who underwent surgical ventricular reconstruction with associated coronary grafting. Patients and methods: This retrospective study selected 37 consecutive patients (32 men, mean age 59 ± 10.5 years) who underwent surgical ventricular reconstruction with associated coronary grafting, and preoperative left ventricular (LV) ejection fraction <30% (mean, 25 ± 4.6%). The mean New York Heart Association (NYHA) class before operation was 3.4 ± 1.3. The time-frame of the large anterior myocardial infarction was 5.8 ± 3.3 months. LV systolic function was assessed by echo-dobutamine: the wall motion score index at rest (WMSIr), WMSl and the extent of LV asynergy (A%) during low-dose dobutamine (Idd). In-hospital mortality was 13.5%. After one-year, the mean functional NYHA class was 2.2 ± 1.1, and at one-year the mortality was 6.25%. Results: Logistic regression analysis and the Proportional Odds model showed that LV A% during Idd (OR 0.86, p = 0.0086) was an independent predictor for the one-year postoperative functional NYHA class. Conclusion: The preoperative extent of left ventricular asynergy during echo-dobutamine can predict the expectation of functional NYHA class improvement in patients with a severe ischemic heart failure one-year following surgical ventricular reconstruction with associated coronary grafting. |
